Description

In this project, I want to recreate the game Don’t touch the spikes on a Raspberry Pi, using an LCD display which will work using Embedded-graphics. The player controls a bird using a joystick, while a separate button is used to restart the game after it ends. The bird moves within four walls with spikes and must collect randomly appearing food to increase the score, which is shown on a 4-digit 7-segment display. As the player progresses, the difficulty increases: at a score of 5, an enemy character appears that the bird must avoid; at 10 points, a second enemy is introduced; and at 15 points, three LEDs light up. Buzzers are used to provide sound effects when the player scores or loses. The game ends when the bird touches a spike or an enemy character.

Motivation

When I was a child, Don’t touch the spikes was one of my favorite games. I remember spending hours playing it with my cousin, always competing to beat each other's high scores. I was fascinated by how such a simple game could be so fun and addictive, and I wondered how it was made. Now, as a university student, I’m excited to finally have the opportunity to learn the skills needed. This project allows me to apply the technical skills I’ve gained while also reconnecting with a childhood memory.

Architecture

• Raspberry Pi Pico 2W

Acts as the main microcontroller that runs the game logic, handles input from components, drives the display, and controls game events like scoring and game over.

• LCD Screen

– SPI - Raspberry Pi Pico 2W

Displays the game's graphics using the Embedded-graphics library.

• Joystick

– ADC - Raspberry Pi Pico 2W

Serves as the player's input device to control the movement of the bird within the game area.

• 4-Digit 7-Segment Display

– GPIO - Raspberry Pi Pico 2W

Shows the player's current score in real-time as they collect food during the game.

• Buzzer

– PWM - Raspberry Pi Pico 2W

Provides sound effects for scoring or losing

• Breadboard

Used to connect all the electronic components

• Push Button

– GPIO - Raspberry Pi Pico 2W

reset button

• Wires

Used to connect all components to the Raspberry Pi Pico

• LEDs

– GPIO - Raspberry Pi Pico 2W

Light up when the player reaches certain scores

Log

• Week 5 - 11 May: Planned the architecture of the project, bought all the required components and created the documentation of the project.
• Week 12 - 18 May:
